COOLER.

To @ZZ 'whom t may concern.'

Be it known that 1, KUwAKioi-n FUJITA, a subject of the Emperor of Japan, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Coolers, of which the following is a specification.

rlhis invention relates to coolers and more particularly to cooling devices designed and constructed for emplovinow the cooling effect of water or moisture as it evaporates.

Some of the objects of the invention are: to. produce a device of the character mentioned. whichis designed to insure a temperature considerably lower than that without the device by disturbing the air within the device to facilitate and cause a more thorough evaporation; to produce a device of the character mentioned which embodies apparatus for more effectively saturating a fabric which incloses the storage compartment forming a part of the device. T@Vith these and other objects in view the invention resides in the combination, arrangement and operation of parts hereinafter more fully described and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the device embodying the present invention; Fig. 2 is a central vvertical sectional view; Fig. 3 is a detail view of the means for actuating the liquid spraying device; F ig. 4 is a detail view of thev escapement means forming a part of the means for actuating the liquid spraying device.

Generally stated the device consists of a storage compartment 10, a supported fabric 11 which incloses the storage compartment, an apparatus for saturating or spraying the fabric, which apparatus includes' a foraminated member 12 and means 13 for rotating the member 12.

Referring nowto the drawing, it will be seen that, the storage compartment 10 is formed within the housing or casing 14, which is open at the top and which is also provided with air passages 15 and a door 16. The fabric 11 is supported from a ring 17. The ring 17 is' supported by the upper part of a frame 18. The frame 18 serves to hold the fabric 11 in a compartment forming condition. A tank 19 is supported upon the 'top of the housing 14. The tank 19 is equipped with a drip cock 20.

rlhe apparatus for saturating the fabric 11 consists of the member 12 which in the pres Specification of Letters Patent.

Patented July 5, 1921. ieee. serial No. 389,173.

ent instance is constructed from suitable foraminous material. The member 12 is formed into the shape of a dome and its base 1s sufficiently large to encircle the fabric 11 as supported by the ring 17. lt will be noted that the fabric 11, due to the shape of the frame 18, is spread out and encompasses a much larger area cross-sectionally throughont the major portion of its length. The particular arrangement of the fabric on the frame 18 insures an effective saturation of the fabric. The member 12 is carried by a shaft 21. @ne end of the shaft 21 is supported on the point of the bearing member 22 at the top of the frame 18, while the upper end of the shaft 21 is held in position by a bearing member 23, as shown in F ig. 3 of the drawing. A spring motor 24, or the like, is utilized for imparting motion to a train of gears 25, which in turn impart motion to a disk 26 mounted for rotation on a shaft 27. The disk 26 is provided with pins 28. rllhe disk 26 forms a part of an escapement means which also includes a disk 29 mounted for movement on a shaft 30. The disk 29 is provided with a V shaped notch 31 and a projection 32, the purpose of which will appear. A gear 33 is mounted on the shaft 30 and said gear 33 meshes with a gear 34 secured to the shaft 21. A flexible element 35 has one end thereof secured to the shaft 21 and the oppositel end of said element is attached to one end of a helical spring 36. The free end of the spring 36 is secured to a part of the housing 14.

In operation, the water in the tank 19 is allowed to pass through the drip cock 20, onto the member 12. By virtue of the motor 24 and the intervention of gears motion is transmitted to the disk 26. In the rotation of the disk 26 one of the pins 28 is caused to enter the notch 31. As the disk 26 continues to rotate and inasmuch as the particular pin 28 engages one of the walls of the notch 31, movement of the disk 29 results. As shown the disk 29 moves in a counter-clockwise direction. Through the intervention of shaft 30 and gears 33 and 34, upon movement of the disk 29, movement is imparted to the shaft 21, and consequently to the member 12. As the shaft 21 rotates, the element 35 will be wound on the said shaft against the contractual tension of the spring 36. As the disk 26 continues to rotate, the particular pin 28 moves out from the notch 31. lmmediately the pin leaves the notch, the spring 36 comes projection 32 Will encounter another of theV Y opposite into play and causes the disk 29 to move in a clockwise direction With the result that the pins28. This latter action causes theV Water precipitated against the fabric ll below.`

The continuedrotation ofthe member l2 in directions alternately, insures. the proper saturation of the fabric l1, and stirs up the air Within the compartment 10 as Well, thereby augmenting the evaporation of Water. v Y

It should be noted that theV frame 18 upon Which the fabric 11 is supported. is of such construction as to provide a reduced upper section and a relatively enlarged lower section. Such disposition of the v fabric makes the saturationltliereof an achievement easy to obtain, inasmuch as' the portion of the fabric at the juncture of the reduced and enlarged sections, presents a broadersurface as disposed asagainst its being disposed verf Vtically.

`Provision made for draining the. bottom of the casing Whereat the drippings from the fabric accumulate, and to. this end therefore, a drip` tray- 37 ispositioned beneath the fabric. The tray is providedvvith I' an outlet 38. Y
